4150 Round Bar: Material Profile
4150 develops greater hardness than 4140 while retaining the toughness and through-hardening benefits of the 41XX alloy family.
Because machining and final properties depend heavily on supply condition, include hardness, mechanical range, size, and heat-treatment status.
Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.
Key Characteristics
- High hardness potential
- Good through-hardening
- Strong wear resistance
- Good fatigue strength
Common Applications
- Heavy-duty gears
- High-strength shafts
- Gun-barrel and pressure components
- Mining and oilfield parts
Specification Requirements
Identify the governing specification and revision, product form, section size, condition, mechanical properties, testing, and certification requirements. The purchase specification and material certification govern the order.
Request Pricing for 4150 Round Bar
We quote 4150 for manufacturers and commercial buyers. Requirements of 3,000–10,000 lb are welcome, along with multi-ton and truckload programs.
We are not a retail metal store. Small personal-use, typical single-bar, and cut-piece orders are generally not a fit. The material field is prefilled and remains editable; add the specification, size, condition, total weight, processing, testing, required date, and ship-to location.
